Abstract: System for optically aiming a laser beam on to a target. The system comprises a mirror which reflects the laser beam towards the target and which is supported by a base by means of a pivot and first and second vibrating control members. This pivot and the control members together determine a first mirror rotation axis and a second mirror rotation axis perpendicular to the first axis. Means are provided for respectively generating a first and a second reference signals for driving the mirror. A laser radiation detector receives the laser radiation reflected by the target and produces a reception signal from which are derived first and second reaiming signal components. The first and second vibrating control members are operated by respectively the sum of the first reference signal and the first reaiming signal component and the sum of the second reference signal and the second reaiming signal component.

Abstract: Two metallic half-moulds are produced from a prototype. The half-moulds have complementary mould faces which abut when the mould is closed, and moulding surfaces formed with annular rim depressions joined by a bridge cavity, each rim depression bordering a support surface for a false lens. A webbed frame front is moulded, false lenses are cut from that moulded front, and the mould faces which abut are set-back by a total amount corresponding to the shrinkage of the false lenses, so that the false lenses are gripped between the support surfaces and shape lens bezels in the rims when a frame front is moulded.

Abstract: In a device for injecting liquid fuel in a combustion chamber of an internal combustion engine, a pressure accumulator chamber connected through a narrow passage with an injection conduit between an injection pump and an injector and intended to suppress or reduce the pressure oscillations appearing in the injection conduit at the end of an injection stage.

Abstract: In an optical fibre connector, the optical fibre is accurately positioned by clamping it in the channel formed between three parallel rollers each of which bears tangentially on the other two. If the fibre is of exactly the expected diameter such clamping is firm and precise, but given the variation in fibre diameters that must be accommodated there is a danger of there being excessive fibre play. This connector overcomes the problem of fibre tolerances by inserting resilient means in the said channel. Such resilient means may for example be constituted by a set of three resiliently deformable elastomer rings, one mounted on each rod.

Abstract: A shim is clamped between a component of a vehicle bumper assembly and a support member to provide a desired spacing for bumper alignment. The weight of the shim and the cost of material for its manufacture are minimized by forming the shim from sheet metal half the thickness of the desired spacing, and by folding the metal to provide double thickness in selected load bearing regions. A number of openings may be provided in other regions further to reduce the weight. Additional folded areas may be used for applications where loading is not restricted to areas adjacent the bolts, and serrations may be embossed in the shim to facilitate mounting of the shim and enhance its stiffness.

Abstract: A liquid immersible scroll pump in which all of the pump components including electric motor drive means are contained within a housing and through which the liquid is pumped at a controlled predetermined pressure.
